The calculation should not been based on pivots or fibo but solely on percentage change of daily open price.

Sometime ago Cja made something like this but it was based on ADR of prior periods and you can only input two levels. I need something where calculation of percentage change is based solely on daily open price.

Once again thanks for help

Have you seen Mladen's "mano rounder" toy

Yes, I’m using it and it is very good, one of the best grid tools for mt4.

But it is not what I’m searching for. I’m looking for the percentage change of price counting from the daily open line, and calculation is based solely on the daily open price.
